I dont mind netting angelfish or discus, they are pretty easy. I dread netting anything out of my salt tanks, specially the wrasse. Moving the big silver aro wasnt fun as he liked to jump, But the hardest thing I have to net imo was a 6" TSN in a 265gal that was full of rocks. I musta spent a hour trying to catch him.
My little female mama convict is the worst for me. She wasn't hard to catch... because she rammed the glass so hard she knocked herself out I think. She was upside down and not swimming afterwards anyways,after about an hour she was able to swim normally again though. Like I said, not hard to catch, I just worry she will hurt herself.
